OIL MIXER AND EiVlULSiFlER.

SPECIFICATION forming part of Letters Patent No. 336,438, dated February 16, 1886.

Application filed December 15, 1885. Serial No. 185,779. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE WM. SAMPLE, a citizen of the United States, residing at York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Oil Mixers and Emulsifiers, of which the following isa specification, reference being had therein to the accompanying drawings.

The object of this improvement is an appliance of simple construction and operation for mixing and emulsifying oils and oily sub stances. These results are attained by the mechanism illustrated in the drawings herewith filed as part hereof, in which the sameletters of reference denote the same parts in the different views- Figure 1 is a vertical sectional representation of an oilmixer and emulsifier embodying the features of my improvement. Fig. 2 is a plan View. Fig. 3 is a transverse sectional representation taken on the line at m. Fig. 4 is a sectional detail view.

A is a receiver for oils or oily substances. This receiver is made, preferably,of metal,cylindrical in form, and provided with a perpendicular projection, a, havinga conical socket, as shown, for a purpose hereinafter set forth. The top of the receiver is provided with a screw-thread for the attachment of a corresponding cover or inclosing cap, 13, which forms a close oil-tight joint therewith.

O C are supports for the receiver A, and are preferably made integral with a band or ring, O,which fits the receiver A, asshown in Figs. 1 and 3, and is provided with a suitable number of set-screws, c c, which secure the connection of the receiver and the supporting mechanism 0 O O.

D is a metal shaft, having a cone-shaped lower end corresponding to the socket in the bottom of the receiver, as shown at a. The upper part of the shaft D is reduced in size and provided with a beveled shoulder, b,which fits closely Within the lower part of the cap B and prevents the oily matter from working out on the cap.

D D are integral radial extensions or arms of a ring, D,which fits snugly around the shaft D, and is rigidly affixed thereto by set-screws d The ends of the arms D are slotted for the reception of perforated agitatonblades D which are adj ustably secured within the slotted ends of the arms D by set-screws d. The perforations in the agitatorblades are for the purpose of facilitating the circulation of the oils and mixture of the oily substances when the machine is put in operation. The blades D are beveled or curved at one edge, as fully shown at d in Fig. 4, for a purpose hereinafter set forth.

G is a power-shaft, provided with a gearwheel, F, which meshes with apinion, E, affixed to the shaft D.

H is a funnel for introducing the oil or oily matter into the receiver. K is a drain-pipe for drawing out of the receiver the oil or oily substances after they have been mixed or emulsified. The pipe K is to be provided with a stop-cock or other suitable mechanism for preventing the egress of matter contained in the receiver, except as desired.

By reason of the adjustable connection of the blades D with the arms D the blades may be set out and made to bear against the walls of the receiver A, and the oil thus subjected to a rubbing process, as well as being mixed by thorough agitation and circulation. The curved edges d of the blades D will facilitate such rubbing process by causing the oily matter to pass between the edges of the blades D and the walls of the receiver.

The mechanism is specially intended for and adapted to useiu the apothecary business; but it is also applicable to mixing oils generally. In the apothecary business a receiver having a capacity of five to ten gallons will be of sufficient size for all purposes, but may be made of any size and adapted to the use of regular oil mixers and dealers. In small machines the gearing may be dispensed with, and the shaft provided with a crank for operating the mechanism by hand.

In mixing oils or oily substances the matter is put into the receiver and the mechanism put in operation until the desired result is produced. For emulsifying oils, for which purpose it is more especially useful and valuable in the apothecary business, the oil is first put into the receiver, and then a suitable quantity of gum-arabic or other necessaryingredients sufficiently to be mixed with the oils, after which water,

sirup, or any medicine is added, and the contents subjected to a rapid rubbing and agita- 2 assess tion by motion of the blades until the contents of the receiver are thoroughly emulsified. It is obvious that this process will produce the desired result more quickly and perfectly than 5 can be done by the 01d method of the mortar and pestle.

The machine may be made in whole or in part of wood or metal.

Having explained the features of my im- 10 provement, what I claim as new, and desire to secure by Letters Patent, is
